Regular quadrilateral prism has an altitude h = 11 cm and base edges b=8 cm. Find the sum of all edges.

The first thing we will do is assume that the prism is square based.

We have then that the edges of the base are:

P = 4L

P = 4 (8)

P = 32 cm

The edges of the top of the prism are:

P = 4L

P = 4 (8)

P = 32 cm

The edges of the prism height are:

P = 4h

P = 4 (11)

P = 44 cm

The total sum will be:

Pt = 32 + 32 + 44

Pt = 108 cm

Answer:

the sum of all edges is:

Pt = 108 cm
